Dynamic behaviour of water transport and power output optimisation in patterned wave channel of a miniature parallel proton exchange membrane fuel cell design using CFD approach.

For the past few years, the world’s energy consumption portrays drastic increment due to the rapid and increasing growth of industrialization as well as society. The energy consumption is expected to be increasing at a rate of 1.4% per year until 2035. In relation to that, most of the energy generated were from the non-renewable sources which is consisting of crude oil, coal and many more. They are known in producing high value of energy but with the rate of energy consumption yearly, the number of these sources are depleting rapidly annually with predicted availability of 50 more years. Plus, the main concern is the harmful pollutants that are released from the excessive burning of these energy sources. For instance, carbon monoxide and carbon dioxide from the burning of these sources will affect the atmosphere. This leads to climate changes and global warming which will harm the ecosystem. Thus, to overcome this crucial matter, lots of other alternative energy source are made where one of it is the fuel cell technology. The mechanism of fuel cell is known to convert chemical energy to produce electrical energy. The chemical reactants are oxygen and hydrogen gases. The process that take place in the fuel cell is electrolysis between the oxygen and hydrogen. In relation to that, the by-product from that chemical reaction produces water which is harmless to the ecosystem. Thus, fuel cell is one of the crucial alternatives in producing sustainable energy for a safer and greener future. One of the most common fuel cells that is being used is the PEMFC. In relation to that, there are a few parameters that might affect the overall performance of a PEMFC such as the pressure drop, the current density, the water distributions and temperature distributions in the PEMFC that will be further discussed in this research. Thus, this research is conducted to study on the dynamic behavior of water transport and power output optimization in PEMFC. This research is wholly simulation-based project where the geometry and mesh of PEMFC will be created using ANSYS software. As for the CFD simulations, it will be based on the parameters mentioned earlier. The results will be compared theoretically to determine the accuracy of this research. Lastly, the dynamic behavior of water transport and power output optimization will be determined at the end of this research along with a thorough conclusion.
